Brian C. Smith's List: Computer Science & Programming

• Nobody even bothers to ask the question Seymour Papert first posed 45 years ago, “Does the child program the computer or does the computer program the child?” This is a tragedy.
• When Luerhmann coined the term, “computer literacy,” he intended it to mean computer programming the intellectual pursuit of agency over the computer and a means for solving problems.
• When a conservative politician and I agree on education policy, who could possibly be on the other side?

• Some of the commercial products are also simplified versions of the sorts of things children usually do in their first few days, perhaps even weeks, of Logo.
• The reasoning behind these Instant versions is that for a young child who does not yet know the alphabet and the keyboard, typing the command FD 10 is too time-consuming and frustrating. So these six keystrokes (including the space and carriage return) are reduced to one: F. But this robs the child of the opportunity to think about the experiment with numbers that is implicit in Logo.

• Starting in primary school, children from all backgrounds and every part of the UK should have the opportunity to: learn some of the key ideas of computer science; understand computational thinking; learn to program; and have the opportunity to progress to the next level of excellence in these activities.
• first we need to face up to a painful fact. It is that almost everything we have done over the last two decades in the area of ICT education in British schools has been misguided and largely futile.
• a "category mistake" – an error in which things of one kind are presented as if they belonged to another.
• We have to replace it with a subject that is relevant, intellectually sustaining and life-enhancing for students.
• So we need to admit that "ICT in schools" has become a toxic brand.
• let us call it computer science. This is an umbrella term that covers two distinct areas. First a set of key concepts that are essential if schoolchildren are to understand the networked world in which they are growing up. And second, computer science involves a new way of thinking about problem-solving: it's called computational thinking, and it's about understanding the difference between human and artificial intelligence, as well as about thinking recursively, being alert to the need for prevention, detection and protection against risks, using abstraction and decomposition when tackling large tasks, and deploying heuristic reasoning, iteration and search to discover solutions to complex problems.
• here's one possible list for starters. Kids need to know about: algorithms (the mathematical recipes that make up programs); cryptography (how confidential information is protected on the net); machine intelligence (how services such as YouTube, NetFlix, Google and Amazon predict your preferences); computational biology (how the genetic code works); search (how we find needles in a billion haystacks); recursion (a method where the solution to a problem depends on solutions to smaller instances of the same problem); and heuristics (experience-based techniques for problem-solving, learning, and discovery).
• If these concepts seem arcane to most readers, it's because we live in a culture that has systematically blindsided them to such ideas for generations.
• if you think they are too sophisticated to be taught to small children, then that's because you've never seen gifted and imaginative teachers go to work on them.
• many UK readers in their 30s will have been exposed to recursion, for example, because once upon a time many UK schools taught Logo programming, enabling children to learn how a mechanised turtle could be instructed to carry out complex manoeuvres. But in the end most of those schools gave up teaching Logo and moved backwards to training kids to use Microsoft Word.
• the fashionable mantra that emerged recently – that "code is the new Latin" – is so perniciously clueless. It implies that programming is an engaging but fundamentally useless and optional skill. Latin is an intriguing, but dead, language; computer code is the lingo of networked life – and also, it turns out, of genetic replication.
• it's not the main reason why we need to make radical changes in our educational system.
• It is that if we don't act now we will be short-changing our children. They live in a world that is shaped by physics, chemistry, biology and history, and so we – rightly – want them to understand these things. But their world will be also shaped and configured by networked computing and if they don't have a deeper understanding of this stuff then they will effectively be intellectually crippled.
• They will grow up as passive consumers of closed devices and services, leading lives that are increasingly circumscribed by technologies created by elites
